To all whom it may concern Be it known that l', FREDERICK H. SEY MOUR, of Detroit,in thecounty of Wayne and State of Michigan, have invented a new and useful Improvement in lllonk'ey-Wrenches, of which the following is a specification.

' Figure 1 is a spective of my improved monkey-wrench. ig. 2 is a side elevation of the upper part thereof", and Fig. 3 is a section on the line of the under surface of the lower jaw.

My invention consistsin a monkeywrench having a handle made from one piece of. wire looped, twisted, and runningin two parallel bars through holes in the lower jaw and riveted into the upperjaw.

A represents the upper and D the lower jaw of a monkey-wrench, through each of which are bored two holes of the same size and at equal distances apart, extending from the lower through the upper surface of each jaw. A piece of wire just large enough topass through the holes in thejaws is then bent at its center into a loop, K, twisted in one or more turns, H above loop .K, and its two ends carried up parallel, B O, at the same distance from each other as are the holes in the jaws. One of the pieces B O has a screwthread cut thereon. In the lower part ot'jaw Dis cuta T- shaped slot, 1*], on the line of one of the holes passing through said jaw.

, G represent a sleeve having a female screw therein adapted to engage with the threaded piece B. A neck and shoulder, F, on sleeve G fit into slot E,so thatsleeve Gr, when placed in said slot, can rotate independently ofjaw l), but cannot move vertically, or along piece 13, without moving said jaw. The lower portion of sleeve G is milled to afford hold for the fingers in rotating said sleeve.

To put'the wrench together, sleeve G is slipped'into slot in jaw D, and the sleeve andjaw are then run down on pieces B G.- The pieces B G are then slipped through the holes in jaw A, and their ends are 'riveted. or
